hi all need some advice on a leak with the ace on my car (TD5 1998).There was a leak a couple of months ago(fast leak) ie you filled it to the max and within a few miles it was below the minimum.took it to get repaired( replaced 2 pipes going into the ace box underneath the car) cost £350. now there is a leak not as severe ie when at max takes about 100miles to get to the minimum.I was wondering is there a product similiar to radweld that can block any slow leaks, dont fancy spending another £350. thanks
